    [SOLVED] Probability distribution of x sketch?

    College students with a checking account typically write relatively few checks in any given month, whereas full-time residents typically write many more checks during a month. Suppose that 50% of a bank’s accounts are held by students and that 50% are held by full-time residents. Let x denote the number of checks written in a given month by a randomly selected bank customer.


    a) Give a sketch of what the probability distribution of x might look like.


    How the hell am I supposed to know this? Is it just a bell curve?

    Sorry for asking so many questions, I think a week into this course I've learned, above all, that tutoring shall be a necessity to get this work done... :/

    It seems to me that it will be a camel hump shape. The first rise is for the students, then it will decrease for a little while and come back up to hit the peak of non-students.

    Ah I see, so just a guess according to who writes more. It seemed too easy, sort of like the last problem did, and those tend to throw me because I'm expecting a more complicated answer than that. >_>
